The essence of photographic expression: fine lenses for a truly powerful system camera.

The SIGMA GLOBAL VISION series of high-performances lenses comprises three distinct lines and concepts: Contemporary, Art, and Sports. SIGMA has developed each of the lenses in these three lines using the Foveon X3 direct image sensor to ensure their world-class optical performance. Offering the outstanding expression that photographers demand, the SIGMA sd Quattro series is a complete and powerful system compatible with these fine lenses.

With its three-layer structure, the Foveon X3 Quattro direct image sensor captures all of the information carried by visible light. This film-like capture system offers rich gradations and color and truly distinctive image quality. Optimized to match the enhanced resolution and other characteristics of the image data, the image processing system of the new SIGMA sd Quattro leverages the outstanding fundamental functions of the camera while taking overall image quality to the next level.

Two sensor sizes available The SIGMA sd Quattro incorporates an APS-C size sensor for outstanding medium format level image quality, while the SIGMA sd Quattro H features a new APS-H size sensor for 51 megapixel-equivalent ultra-high image quality.

Other cameras typically use a single-layer photo sensor covered by a Bayer filter mosaic, which comprises 50% green, 25% blue, and 25% red squares. In contrast, the Foveon X3 Quattro direct image sensor uses no low-pass filter and is able to capture 100% of the data for blue, green, and red in each of its three layers. Due to this unique structure, the Foveon X3 Quattro direct image sensor can generate up to twice the resolution data of sensors using a Bayer filter. The SIGMA sd Quattro has an APS-C-size sensor with 19.6 megapixels in its top layer, giving it an equivalent total of approximately 39 megapixels and the outstanding image quality expected of a medium format camera. The SIGMA sd Quattro H features a newly developed APS-H size sensor (26.6 x 17.9mm) with 25.5 megapixels in its top layer for an equivalent total of approximately 51 megapixels. This larger sensor takes Foveon image quality to the next level, delivering more detailed images than ever before.
